Hi,
first look at your hard drive you will see pin assignment=2E(Jumper setting)and its depend on manufacturer=2Eon HDD you will find that put jumper according to your choice=2Ewhich one you want to make master and slave=2Efor master put jumper for master and for slave put jumper for slave=2Erestart your computer=2Ego to bios setting and change setting master and slave for right hdd=2Esave changes it will work=2Eif not send details of your HDD=2Eon patelik2003@yahoo=2Ecom

Your system will support 4 drives, either in CS (Cable Select) or
DS (Drive Select) configuration. There are 2 HDD Cablesets
coming off the board, PRI and SEC. PRI is usually used for HDD,
and SEC for CD and DVD Drives. You will have to look at the HDD
and see which config your system uses - CS is the most popular
and uses a special cable with 1 pin dropped between the PRI and
SEC connectors, and simply plugging the HDD into the 2
connectors automatically addresses them, however both HDD must
use the CS jumpered setting.
DS is older, uses a straight-thru HDD cable and each HDD is
jumpered to MASTER or SLAVE and it does not matter which of the
two connectors the HDD are plugged into. A quick fix is to
simply attach one of the two HDD to the 2d cableset connector.
Only the PRI will boot, and you can then access the other. If it
doesn't work the way you intended, swap the HDD around and try
again. Be sure to power down first tho' ;-)
